Introduction The Department of Defense can’t keep up with the war on terror using regular methods. They are looking for people that can excel under pressure using everyday objects in innovative ways. They are looking for people who fill this description. Is it you? Your first task is to make a rocket out of two liter bottle… Title Introduction Task Process Research Drawing Building Write-up Evaluation Conclusion Teacher Page

Task You must create your own water bottle rocket that will be launched in competition with your classmates. The base of the water rocket will be a two liter soda bottle. You will include blueprints, a force diagram, and a one page written explanation of the physics of your rocket.

Process Your project will occur in 4 phases: 1.Research 2.Drawing 3.Building 4.Write-up Title Introduction Task Process Research Drawing Building Write-up Evaluation Conclusion Teacher Page

Process: Research In order to build a successful rocket you must know what makes it fly. Use the following sites to research these questions (and whatever else you think will be helpful): –What makes the rocket (soda bottle) fly? –How can you maximize propulsion? –How does the body shape affect its flight? –What do fins do?

Process: Drawing Now that you know what you’re looking for (hopefully), it’s time to come up with a plan. Make a scaled drawing of the rocket you will build labeling all materials. You may use graph paper by hand or use a program such a Visio. Remember: You must use a two- liter soda bottle as your base.

Process: Building Assemble the rocket according to your blueprint. Remember…You MUST use a two-liter soda bottle as the base/to hold the water. Some encouragement that water rockets really do work: 2L Bottle Mythbusters’ ultimate water rocket Don’t even think about it Title Introduction Task Process Research Drawing Building Write-up Evaluation Conclusion Teacher Page

Process: Write-up You are to write-up your rocket design. The write-up should justify all parts of your rocket. This includes, but is not limited to, body modifications and how much water was used. These should be explained using the physics concepts that you learned during your research. You may use the form below to organize what needs to be in the write-up.

Evaluation Beginning 1 Developing 2 Proficient 3 Exemplary 4 Drawing Drawing is incomplete and unscaled Drawing is complete Drawing is scaled Drawing is scaled and complete Force Diagram Correctly identifies no forces Correctly identifies some forces Correctly identifies most forces Correctly identifies all forces Write-up: How much Water Fails to explain amount Explains amount but does not include law Explains amount but does not properly apply law Explains amount and applies law correctly Write-up: Body Alterations Identifies some alterations Identifies all and explains some alterations Identifies and explains all alterations Identifies, explains, and justifies all alterations Flight Time Does not launch Less than 5 seconds Between 5 and 10 seconds Over 10 seconds Title Introduction Task Process Research Drawing Building Write-up Evaluation Conclusion Teacher Page

Conclusion Congratulations, Your application of your physics knowledge was superior. With a few more years of school you’ll be ready to save the world… Title Introduction Task Process Research Drawing Building Write-up Evaluation Conclusion Teacher Page

Standards Addressed (Physics and Geometry): PH.3 The student will investigate and understand how to demonstrate scientific reasoning and logic. PH.4 The student will investigate and understand how applications of physics affect the world. PH.5 The student will investigate and understand the interrelationships among mass, distance, force, and time through mathematical and experimental processes. G.12 The student will make a model of a three-dimensional figure from a two-dimensional drawing and make a two- dimensional representation of a three-dimensional object. Models and representations will include scale drawings, perspective drawings, blueprints, or computer simulations.
